The ability to Dispel friendly targets is going to be a passive skill that you get for speccing into either Discipline or Holy.

I shall die here. Every inch of me shall perish. Every inch, but one. An inch. It is small and it is fragile and it is the only thing in the world worth having. We must never lose it or give it away. We must never let them take it from us.

how is preshielding everyone before a pull drink up balanced? aswell as this will stop priests in pvp to blanket shield themselves for 50-60k more hp at start. good change.

I didnt say PW:S blanketing was balenced.... clearly it wasnt. It certainly wont be a doable with this 4.1 change - my concern was regarding the effectiveness of the SoS talent more than the duration of the shield itself.

yes there will be a point to reducing the weakened soul. Shield a tank. How often does his shield last even 15 seconds? Lower the weakened soul and you can get more shields on him.

Overall I don't have a problem with lowering the overall duration. There should be no abilities that require pre shielding for anything on a massive scale. 15 seconds still seems plenty long to me. Shields usually don't last that long anyway from my perspective. Can't speak from a pvp point of view, I really only do pve content. pvpers can give their view on it.

It's not your mastery, your mastery depends on spec and increases with Mastery Rating. It is going to be a passive for speccing into the tree, like how Restoration Druids get Disentanglement.

Dispel Magic - Self Only, but wait Disc gets 'Absolution' to enable us to remove 2 magic effects.... so that means Holy Priests can heal their hearts out while disc is left to dispel all the shite ?!

Lets calmy read everything first, then make your QQ post
As for the shield "nerf", i have yet to do an encounter where the shield is up 15 seconds. Specialy in HC encounters i end up using at least 2 heals to reduce the weakened soul so i can recast shield on tank (think Maloriak HC, dark sludge phase)

This nerf won't change anything with PWS usage. It only makes raidwide pws spam harder, which is not a bad thing.
Longer DA is a great stuff on the other hand. Less DA procs lost after using PoH in a non-continous aoe damage environment.

I like this change very much.
PW:S is a very strong spell in the disco priests arsenal, and it should be. But what Blizzard is trying to avoid is spamming one ability. The quick solution was an increase in mana cost, but that is only shifting back the point in time when bubble spamming becomes doable again. The problem is with the spell itself, you can easily get a shield out on two thirds of your raid (or the whole raid in 10man), and since the spell is very powerful now, blanketing will always be an option if you can handle the mana cost. And raid blanketing SUCKS. It makes me cringe. I like Divine Aegis, Grace and the mechanics of discipline, I want to play with them and I don't want the best strategy to be to just spam around one single spell.
A shorter duration is a step in the right direction, because it lowers the number of targets you can shield at a time, and because the window in which "the damage" has to occur is smaller. A nerf I would like even more would be a hard cap on active shields (four or five maybe).
A 15sec PW:S doesn't change a thing in tank healing, and it still alows you to preemptively "heal" people before a big hit. So the spell can still do everything it should be able to.

I'm okay with this nerf. So far in current content, there are few situations where I really want to pre-shield the entire raid. And in those few situations, I can just drop a barrier. When I go into shield-spam mode, my shields are getting eaten up in less than 10 seconds. If reducing the duration of PW:S will keep Blizzard from increasing the mana cost or nerfing the absorb, it's fine by me.

imo it is way to early to comment on this changes i might feel a little bit worried but i welcome DA buff with huge grin on my face since this is why i stacked MST and Crit in first place to get more DA procs and benefit out of it shield in case of my raid environment was never an option to spam but more as a life saver outside of recasting it on tank every rapture cd.
